Newton/square Millimeter
Newton per square millimeter (N/mm²) is a unit of pressure or stress, representing the force of one newton applied over an area of one square millimeter.
History/Origin
The unit derives from the SI base unit newton for force and the millimeter for area, commonly used in engineering and material science to measure stress and pressure. It has been in use since the adoption of the SI system, with increased application in fields requiring precise measurement of high pressures.
Current Use
N/mm² is widely used in engineering, material science, and construction to specify material strength, stress, and pressure levels, especially in contexts where high precision is required, such as in the specification of tensile strength and pressure ratings.
Ton-Force (Long)/square Foot
Ton-force (long) per square foot is a unit of pressure representing the force exerted by one long ton (2,240 pounds) distributed over one square foot.
History/Origin
This unit originated in the UK as a practical measure for engineering and industrial applications, combining the long ton (used primarily in the UK) with square foot to measure pressure in contexts such as structural and mechanical engineering.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units like pascals. It may still appear in historical data, specialized fields, or regional contexts within the UK.
